Cannot search file in Alfresco 2016 DEC community edition

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I installed Alfresco 2016 DEC community edition but I cannot search any file; I installed Alfresco 2016 May version, it was perfect for me to do search file; anyone can help? please advise me.

I compared search filters in search manager, they are default and same.

I didn't add and change anything, it was so strange!
